Reproduction steps

I am using the vscode extension for a project running ruby 2.7.7, so I am following the separate Gemfile usage. The project uses asdf to manage ruby versions. This has been working great but it broke with the vscode extension version 0.5.20.

Now when I start the extension in this project, it shows an error /Users/addisonbrickey/.asdf/installs/ruby/2.7.7/bin/ruby: invalid option --yjit (-h will show valid options) (RuntimeError).

The core of the issue is the --yjit option is being added to the ruby command even though ruby 2.7.7 does not support it. I did notice in that release a manager for asdf was introduced #1845 in 0.5.20. My project uses asdf so I assume that is part of the issue. Can see the code building the ruby command checks the ruby version number to ensure it supports yjit option.
